SPECIFICATION forming part of Letters Patent No. 492,648, dated February28, 1893. Application filed September 30, 1892. Serial No. 447,395. (Nomodel.)

To all whom it may concern:

- Be it known that I, GUSTAVE P. WERN, of Brooklyn, in the county of.Kings and State of New York, have invented a new and ImprovedOable-Support, of which the following is a full, clear, and exactdescription.

The invention relates to supports for cables such for instance, as areused for propelling cars of carrying devices employed for moving coal tofurnaces of gas houses, or for other purposes.

The object of the invention is to provide a new and improved cablesupport, which is simple and durable in construction, very effective inoperation, and arranged to swing out of position when struck by the cargoing in either direction, and to return automatically to its normalcable supporting position as soon as the car has passed.

The invention consists of an arm for supporting the cable and mounted toswing on a fixed pivot, the arm being provided with a hub havinginclined surfaces adapted to travel on like surfaces formed on a sleevemounted to turn with the said arm in one direction, and adapted to beheld in a fixed position when the arm moves in an opposite direction bya collar secured on the said pivot.

The invention also consists of certain parts and details, andcombinations of the same, as will be hereinafter described and thenpointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the improvement as applied, parts of thetrack being shown in section. Fig. 2 is an inverted plan View of theimprovement; and Fig. 3 is a side elevation of a modified form of partof the improvement.

The carrying ortransporting device of any approved construction isprovided with the usual rails A between which pass the cables B adaptedto move the cars traveling on the rails A. Each of the cables B isadapted to rest on a grooved pulley C journaled on a pin D secured inthe head E formed on one end of an arm F, mounted to turn horizontallyon a pivot Garranged vertically and secured on the bottom flange of oneof the rails A. The

head E is provided with a projecting lug E adapted to rest on akeeper Asecured to the base flange of one of the rails A, as plainly shown inFig. 1, so that the arm F is supported on the cable supporting end, toprevent undue strain on the pivot G by the weight of the cables restingon the pulleys O. The arm F is provided on its under side with a hub Fset on the upper end of a sleeve I-I mounted to turn loosely in onedirection on the pivot G, the said sleeve being prevented from turningin an opposite direction by a collar .1 held on the square lower end Gof the pivot G. The lower edge of the hub F is formed with two inclinedsurfaces F and F mounted to travel on correspondinglyshaped surfaces Hand H formed on the top edge of the sleeve H. The straight vertical backF of the hub is adapted to abut against a corresponding straight edge Hformed on the sleeve H so that the arm F can swing in one direction onthe upper edge of the sleeve I-I without moving the latter as the back Fthus moves away from the edge H the said arm F then rising on the pivotG by the incline F traveling up the incline H. When the arm F swings inthe opposite direction and the straight edges F and H are in contactwith each other, then the sleeve H turns with the hub F. The lower edgeof the hub H is formed with the inclines H and H mounted to travel oncorresponding inclines I and I formed on the top edge of the collar I.The incline H is located directly opposite the incline H and curves inan opposite direction, as plainly shown in Fig. 1, the other incline Hbeing located opposite the incline H and also extending in an oppositedirection. A straight edge H connects the ends of the inclines H and Hwith each other and this straight edge is adaptedjo abut against a cor:responding straight'edge 1 formed on the collar I at the ends of theinclines I and 1 Now, it will be seen that when the arm F swings in thedirection of the arrows a,then the incline F travels up the incline 11so that the arm F rises on its pivot G and the sleeve H is heldstationary on account of the straight edge H abutting against thestraight edge I of the fixed collar I. When the arm F swings in theinverse direction of the arrow a, then the abutting edges F and H ICOcause a turning of the sleeve H so that the straight edge H moves awayfrom the straight edge 1 at the same time the sleeve I-I rises owing tothe inclines H and H traveling up the inclines I and 1 The rising of thesleeve H causes a like rising of the hub F and arm F.

Now, it will be seen that when the device is in use and a cartravels inthe direction of the arrow Z) and finally strikes the head E, then aswinging motion is given to the arm F in the direction of the arrow a,as above described so that the arm F with its head E nearly makes aquarterturn and thus moves out of the path of the car to permit thelatter-to pass. As soon as the car has passed the arm F returnsautomaticallyto itsnormal position, as the inclines F and F traveldownward on the inclines H and H on the sleeve H now held in a fixedposition as above described. When the car travels in the inversedirection of the arrow 1), then it strikes the head on the other sideand causes the arm F to swing in the inverse direction of the arrow auntil the arm permits the car to pass, the arm nearly making one quarterturn. When the arm travels in this direction, the sleeve H turns withthe hub F as above described and when the car has passed, the sleeve Hand the arm F return to their normal position, as the inclines H and Htravel down the inclines I and 1 respectively.

In order to counterbalance theweight of the head E and the pulley O, Iprovide the outer end of the arm F with a counterbalancing weight J orwith a second head E similar in construction to the head E and alsocarrying a set of pulleys C. Now, when the pulleys O in the head E havebecome worn the other head E with its pulleys C may be brought into useunder the track rails A to support the cables B, it being understoodthat the head E is then the outer part of the arm instead of theinnerpart, as above described and shown in the drawings. In order to makethis change,the position of the collar I is changed on the square end Gof the pivot. G by giving the said collar a half-turn before insertingit on the lower end of the pivot G.

Itwill be seen that by this device the cables are supported during thetime the car moves away from the device, and the latter is free to swingout of position when the car strikes it, and automatically returns assoon as the car has passed.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. A cable support comprising an arm mounted toturn and adapted to support the cable, a hub held on the said arm andformed with inclines, a sleeve mounted to turn and adapted to be engagedby the inclines on the said hub, and a fixed collar adapted to beengaged by the said sleeve to hold the latter in position when the armswings in one direction and to permit the sleeve to turn when the armswings in an opposite direction, substantially as shown and described.

2. A cable support comprising a fixed pivot, an arm mounted to turn onthe said pivot and adapted to support the cable, a hub formed on thesaid arm concentric to the said pivot and provided with inclines and astraight edge, a sleeve mounted to turn on the said pivot and formed atits upper end with inclines adapted to be engaged by the hub inclines,and also provided with a straight edge adapted to be engaged by thestraight edge of the hub, substantially as shown and described.

3. A cable support comprising a fixed pivot, an arm mounted to turn onthe said pivot and adapted to support the cable, a hub formed on thesaid arm concentric to the said pivot and provided with inclines and astraight edge, a sleeve mounted to turn on the said pivot and formed atits upper end with inclines adapted to be engaged by'the hub inclines,and also provided with a straight edge adapted to be engaged by thestraight edge of 'the hub, and a collar fixed on the lower end of thesaid pivot and provided with inclines adapted to be engaged by inclineson the lower end of the said sleeve and also provided with a straightedge adapted to be engaged by alike edge on the lower end of the sleeve,substantially as shown and described.
